	Hi Austin,

	You should become familiar with RFC2317 - it seems there is support
	for this according to:

	http://www.afrinic.net/en/services/rs/membership-types/123-afrinic-policy-for-reverse-delegation-on-allocated-ip-addresses

	For delegations of address blocks smaller than a /24 the method described in "Classless IN-ADDR.ARPA Delegation"[RFC 2317] will be used

	However, someone more familiar with the Afrinic DB might have some
	additional input on the exact way to do this :)

	Cheers,
	Phil
